Some tooltips in a qt application
I want the users see some tooltips when they have started my application first time. The tooltips must teach them how to make use of the application. E.g. the OpenShot shows such tooltips: https://youtu.be/-3vbwudyxQk
How can I realize such training mode for an qt application?
You can use
QWhatsThis(http://doc.qt.io/qt-5/qwhatsthis.html) for simple stuff, or any other method to present whatever you want to help user with. It is then up to you in code to decide if a user no longer needs these hints, and disable the tooltip/whatever when no longer wanted.
